' I Application filed February To aZZ whom it may concern 2 Be it knownthat I, VERN W. DUFF, a citizen of the United States, and a resident' ofMoberly, in the county of Randolph and State of Missourh'have invented acertain new and useful Device for Holding Engineers Time Tables, ofwhich the following is a specification. 1 V I This invention relates toimprovement in devices for holding engineers time sheets, and has forits object to provide means of simple, durable and inexpensiveconstruction adapted to hold engineers time sheets in such a manner andin such a position that the engineer or fireman mayv easily andaccurately read the order written thereon without interfering with anyoperation which he may be erforming if further object is to arrange thetwo outer sheetsof a series of time sheets with-their printed sidesoutermost, clamp them between-two transparent members, such as sheets oflass, to hold the sheets straight and keep them' clean, the transparentmembersbeing pivotally mount.- ed in such a manner. that eachsheet maybe turned to a predeterminedposition in such manner that it maybe'easily read by either the fireman or engineer,- and in this connecandto place and tion: provide means formounting a lamp in;

such a manner thatthe'light may be oneither of the sheets toberead'whenin eitherof its positions of movement.

Still a further Qb ect 1s to provide a device as above described, havingtransparent sheet supporting members, new and improved means forsupportlng and mountand improved ing said transparent member's, meansfor placing theflsheets in operative positions between said transparentmembers.

These and other objects, which need not be willbe apparent to. thoseskilled in the art. y My. invention consists in the construction,arrangement and combination of the various parts of the device, wherebythe objects contemplated are attained, as hereinafter more fully setforth, pointed. out in my claims and illustrated in the accompanyingdrawings,

roved device comprises a br'acketber indotted'lines in one position ofits movereceive screws for the purpose ofsefcuring said brackets to anyconvenient place in an engineer s cab. This ls'prefer'ably, however,

supported in such a manner that the device hereinafter described may beeasily and quickly read by either the fireman or the englneer, I

The member 10 is provided with two horizontally arranged parallel arms12 being provided at their outer ends with pivot members 13 and lemountedin a rectangular frame 15. This frame 15is provided with an innerframe member 16, having an inwardly extending flange 17 atone of .itsedges. This frame16 is designed to-receive atransparentplate 18,preferably formed of .glass,.. wh1ch is held in place by any of themethods usedin devices of this kind.

f 1' The frame 16andplate 18 are of a size sub stantially. equal to thedimensions of an engineei' stimefsheeu-the frame 16 being of a -widthsomewhat greater than the thickness ofa series of time sheets such as isnecessary for an engineer to complete a given run. The sheets aredesigned to be placed intheframe 16,'with oneof the sheets to be readadjacent to the glasslS, while another may beplaced on the opposite sideof the sheets and held in position by means of aglass plate 19. Thisplate'19 is mounted in a frame member 20 which is slightly smaller thanthe frame 16 so thatit may be placed therein as shown in Figure 2. "Eachof the members of the frame 16 is provided with bracket members 21 nearsheets may be inserted between the plates 18 and 19. The top member ofthe frame 20 is provided with a strip 23 formed with an inclined face sothat the sheets may be easily removed from the frame 20 by having theirupper edges engage the said beveled face.

For securing the upper end of frame 20 in position within the frame 16,I have provided the latch 24 designed to co-act with the pin 25 and theframe 16. The said pin 25 is designed to be received in a suitableopening in said member 24. This member 24 is provided with a curvedportion with a straight end to enable the operator to easily pull theframe 20 out of the frame 16.

By this construction it will be seen that I have provided means wherebya series of time sheets may be placed between two transparent plates andsupported in an upright position in such a manner that they may beeasily read from either side. This provides means for supporting twosheets.

When the instructions from one of the sheets have been read and it isdesired to read the instructions on the other sheet, the frame 16 isswung upon pivots 13 and 14 through an angle of 180 degrees which placesthe opposite sheet in a position to be read.

The frame member 10 is provided with a small bracket 26 having slidinglymounted therein a latch pin 27 upon which is mounted a spring 28. Theouter end of the pin 27 is provided with a head 29, and its innerportion is provided with a washer 30 held against movement on the pin 27by means of a key 31, the washer being so placed that pressure from theend of the spring will 7 cause the pin 27 to move inward. The other endof the said pin 27 is provided with a central shoe 32 which isdesignedtoengage the notch 33 formed in the outer face of each of the endmembers of the frame 16, thereby providing means for holding the frame16 rigidly in position relative to the'bracket end. a

The shoe 32 is so arranged that a slight pressure applied to the frame16 will cause it to disengage the notch 33 when it is desired to swingthe frame.

I have provided means for illuminating the sheets artificially, whichcomprises a bracket 34 mounted on the pin 14, which is considerablylonger than the pin 13. The said pin 14 is provided with a collar 35which is keyed thereto and is designed to carry the said bracket 34. Forholding the bracket 34 in engagement with collar 35, I have provided aspring 36 which is mounted on the upper end of the pin 14, said upperend of the pin being provided with a washer 37 designed to rest on theupper end of said spring, said washer being secured in position by meansof a collar 38 secured to the pin 14 by means of a key 39.

The bracket 34 is bent upward and provided with a lamp socket 40 havinga reflecting shade 41. The shade and lamp are set at such an angle thatthe rays of light from the lamp 42 will be thrown upon either of theplates 18 or 19, and then said bracket member 34 is held substantiallyat the right angle to the frame 16. Figure 2 shows the lamp in positionto throw the light on the plate 18. If it is desired to swing the frame16 so that the plate 19 may be placed in a readable position, the saidframe 16 is swung in the direction indicated by the arrow in Figure 3.This will cause the member 42 on the bracket 34 to engage one of thepins 43 mounted'on the upper face of the bracket member 12 by thefrictional engagement between the bracket 34 and the collar The framemaythen be swung to position with the plate 19 under the light.

If it is desired to swing the plate 18 so it may be read from theopposite side of the bracket 10 from that shown in Figure 2, it will bedesirable and necessary to move the light with the frame. This isaccomplished by rotating the frame 16 in the opposite direction fromthat shown by the arrow in Figure 3. This will cause the member 42 todisengage the pin 43 and the bracket 34 to followthe frame 16 by thefrictional engagement of the collar 35 until the opposite end of themember 42 is engaged by the opposite pin.

It will beseen that I have provided a device of comparatively simple,durable and inexpensive construction into which a series of engineerstime sheets maybe inserted in position to be read by either the engineeror 'the fireman; If the fireman desires to readthe orders and they arein a position adjacent to the engineer, all he has to do is simplyrotate the frame 16 through an angle of 180 degrees. lVhen he hasfinished, the framemay be then moved to its original position if sodesired. The order sheets are always in a position where they can beread even without the operators discontinuing the work which they may beperforming.

By the arrangement of my improved lamp bracket the light may be carriedwith the sheets as moved from one position to another, or the sheets maybe reversed under the light without any operation on thepart of theoperator any more than turning the frame 16 which requires less timethan it vould to turn a series of sheets.

New sheets may be easily inserted by mov ing the large member 24slightly downward to disengage the pin 25, then permitting the upperedge of the frame 20 to be swung outward until the ends of the frameengage the flange 22, after which the old sheets may be bracket, 2.frame pivoted therein, one of said bracket. and said pin so that as thesaid frameis rotated, the said bracket will be rotated, and means forlimiting the movement of said bracket after it has moved through apredetermined angle.

3. In a device of the class described, a

bracket, a frame, having parallel spaced transparent panels, pivotallymounted at its central portion to swing in said bracket, said framebeing provided with means whereby instruction sheets may be placedbetween said panels, a lamp adapted to be moved to position to throwlight on either of said panels, when in any of its positions of movementand also adapted to automatically'follow the panels as they are movedthrough a predetermined angle relative to said bracket.
